In what format is data stored in a computer?
Data is store momentarily in computers in RAM. Random Access Memory are chips that contain registers that retain their electrical state for as long as its either changed or the power is turn off. Data can also be store permanently in a Hard Drive. HD are nothing more than a magnetic disc that spins around while a writing head magnetises the surface of the disc, creating areas to simbolize ones and zeros; the digital language of computers.
What Part of a computer that plays music and data?
A computer can only produce sound if it contains the right hardware. These come in the forms of sound cards or sound chips. In most cases these devices only convert the sound data from digital to analogue signals - the computer itself reads the binary data and decodes it into a form understandable by humans.
What is a group of computers is called?
A group of computers might form a network, but this is not necessarily the case. There is no commonly used collective noun for computers.
Data validation best refers to?
Data Validation is a process that ensures that data entered into the database form, a web form, or a computer program conforms to the correct data type.
Types of computers on the basis of working?
On the basis of working principle computer are classified in to three types Ana log computer, Digital computer, and hybrid computer. Ana log computer measures continuous type of data and uses a physicalquantity like electric current, voltage, temperature, etc. to present and process the data. It represent numbers by a physical quantity; that is, they assign numeric values by physically measuring some actual property, such as the length of an object, an angle created by two lines, or the amount of voltage passing through a point in an electric circuit. The computer which accepts discrete data as per the electric signals is known as digital computer. Basically , digital computers counts digits, which represent numbers or letters. The computers based on binary digits i.e. 0 and 1 are called digitals computer. It represents each and every information in terms of single numbers and processes the information by using standard arithmetic operations. Hybrid computer is the combination of the feature of Ana log and Digital computers.
How can two computers communicate over public telephone network?
Two computers can communicate over a public telephone network by using modems to convert digital signals into analog signals suitable for transmission over telephone lines. Each computer connects to a modem, which dials the phone number of the other computer's modem. Once a connection is established, the modems facilitate the exchange of data by encoding and decoding the signals back into digital form. This allows the computers to send and receive information effectively over the network.
What data does the computer record?
Computers record data in the form of "bits", Binary Digits.
Distinguish between analog computer and hybrid computer?
ANALOGUE COMPUTERS ARE THE COMPUTERS WHICH PROCESS DATA IN A WAVE FORM WHILE HYBRID COMPUTERS POSSESS DATA IN BOTH DISCREET AND WAVE FORMS.
What type of energy does a cellphone produce?
A cellphone produces electromagnetic energy in the form of radiofrequency radiation to communicate with cell towers. This energy is used to transmit and receive signals for voice calls, texts, and data transfer.
Is computer capable of processing only digital signals?
Yes, computers primarily process digital signals, which are represented as discrete values, typically in binary form (0s and 1s). However, they can also interact with analog signals through devices like analog-to-digital converters (ADCs), which convert analog signals into digital form for processing. Ultimately, while the core processing occurs in the digital domain, computers can interface with and handle analog signals when necessary.
Write a sentence about data at least 8 words?
Data is a form of stored knowledge by computers and other forms of technology.
In wired connections the medium that carries data in the form of light signals is?
In wired connections, the medium that carries data in the form of light signals is typically optical fiber. Optical fiber cables use glass or plastic fibers to transmit data using pulses of light, allowing for faster and more reliable data transmission compared to traditional electrical cables.
Which type of network cable transmits digital signals in the form of pulses of light?
Fiber optic cable transmits digital signals in the form of pulses of light. It consists of thin strands of glass or plastic that carry light signals over long distances with minimal loss and interference. This technology allows for high-speed data transmission, making it ideal for internet, telecommunications, and data center applications.
What is data transmission channel?
Transmission channels are defined as paths through which electrical signals can pass through. It may be in form of a physical cable.
What form of energy travels between telephones?
Electromagnetic waves in the form of radio signals travel between telephones to carry voice and data transmissions.
How are computers physically linked What is the most common type of material to do this?
Computers are physically linked through various types of cables and connectors that facilitate communication and data transfer. The most common type of material used for these connections is copper, often in the form of twisted pair cables (like Ethernet) or coaxial cables. Fiber optic cables, which use glass or plastic fibers to transmit data as light, are also widely used, particularly for high-speed and long-distance connections. These materials enable efficient transmission of electrical signals or light signals between devices.
What does a data refer to?
Data refers to information, facts, or statistics that are collected, stored, and analyzed for various purposes. Data can be in the form of text, numbers, images, videos, or any other type of information that can be processed by computers.
